Abstract:
By a series of no consolidated undrained shear triaxial tests of cement lime soil specimens with different salt contents, effects of salt contents on shear strength parameters of cement lime soil were discussed and reasonable explanation on the micro-structure was introduced. The test results show that the intensity parameter of cement lime soil increases with increasing of salt content, but when the salt content reaches a certain level, its strength decreases with increasing of salt content, and there is a boundary value in salt content. Moreover, the brittle fracture resistance of cement lime soil is influenced by factors such as confining pressure, salt content, etc. The smaller the confining pressure is, the higher the salt content is, the more obvious the brittleness of cement lime soil is.
